Abstract

On décrit un dispositif magnétique de sécurité à verrouillage à crans qui comporte des éléments mâle et femelle coopérants et fonctionne par l'attraction d'un aimant permanent. L'élément femelle comprend des pièces coulissantes ou pivotantes (105) qui coopèrent pour définir une ouverture (114). Le dispositif de verrouillage recourt à la force d'attraction magnétique existant entre des surfaces d'au moins une des pièces coulissantes ou pivotantes (105) de l'élément femelle et des surfaces correspondantes de la partie magnétique (121) de l'élément mâle, ce qui produit l'entrée en prise magnétique et mécanique des éléments mâle et femelle. La séparation magnétique et mécanique des éléments mâle et femelle s'obtient par coulissement ou pivotement d'au moins une des pièces coulissantes ou pivotantes (105). L'élément femelle comprend aussi un logement (127) d'un seul tenant qui reçoit les pièces coulissantes ou pivotantes (105) et se prête à une production de masse peu coûteuse.
